PICK-POLE.

Specification of Letters Ifatent. Patented J ne 13 1916 Application filed March 23, 1916. Serial No. 86,243.

such as are used in directing logs into a boom pocket as they pass along the sheer. The poles heretofore used for this purpose have been provided with pointed stems rigid with the pole and the stems and poles have often become broken because of the sudden and unavoidable strains to which they have been subjected, such breakage resulting in the loss of the logs engaged by the stems.

One of the objects of the present invention is to provide a structure of this character utilizing a stem or point which is shiftable relative to the pole so that should the implement be subjected to a strain such as would ordinarily break a pole of the type commonly used, the relative movement of the stem and pole would be such-that injury to the parts would not result.

With the foregoing and'other objects in view which will appear as the description proceeds, theinvention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, with-' out departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown. In said drawings:-Figure 1 is a planview of a pole embodying the present improvements, the stem being shown in engagement with the log. Fig. 2 is a View partly in section and partly in elevation'of a portion of the pole and showing its connection with the stem, certain of the positions to which the pole may move relative to the stem being indicated by dotted lines. Fig. 3 is a section on line AB Fig.2.

Referring to the figures by characters of reference 1 designates a pole of any desired proportions one end of which is fitted within a ferrule 2 which projects beyond the end of the pole and terminates in a socket 3 having opposed portions somewhat flattened, as

indicated ate. The socket is elongated in the direction of the length of the ferrule and constitutes a seat for a head 5 from which extends a tapered stem 6 pointed as shown. An ear 7 extends .from the innermost portion of the head and is engaged by one end of a coiled spring 8 housed within the ferrule 2, the other end of the coiled spring being attached toan eye 9provided at one end of a rod 10. This rod is extended within a portion of the pole and has one end extended outwardly to the sideofthe pole as shown at 11.

Under normal conditions the spring 8 holds the head 5 drawn inwardly against the innermost portion of'the-socket' 3 and maintainsthe longitudinal axes of the stem I and pole in alinement. Thus when the point of the stem is driven into a log a portion of which has been indicated at L the thrust will be directed from the wall of the socket 3 against the head 5 and thus to the point. Should the pole be subjected to a lateral strain, asfor example by the impact of an other log against the side of the pole, the pole would be free to swing relative to the point, as indicated by dotted lines in Fig. 2, thus avoiding all danger of'a break. During the operation of driving the point into a log, the wall of the opening in the i of the socket 3 fits close to. and surrounds the thick end portionof the stem, thus holding the stem against swinging movement. However, when the pole is pulled away from the point, the wall of said opening in the socket is brought to position opposite an an- I nular. groove or channel formed in the inner end portion of the point so that thepoint can thus swing relative to the ferrule. Spring 8, as before pointed out, holds the point normally drawn back into the ferrule and, should the outer end against the inner portion of the socket, said socket and stem cooperating to hold the stem against pivotal movement when retracted against the seat.

3. The combination with a pole having av socket, at one end, a headv within the socket, and'a pointed stem projecting from the head, said head and stem being slidable relative to the socket and said stem being capable of swinging relative to the socket whenin outwardlyprojected position, of yielding means for holding the head normally seated against the. inner portion of the socket and the stem normally out of projected .position.

4.- The combination with a pole and a socketmember at one end-of the pole provided with an opening, of a head slidably mounted within the socketmember, a pointed. steml projecting from the head and through the opening, the wallof the opening-cooperatingwith the stem for holding thestem against swinging movement when the head is in normal position, yielding means engaging the head for holding it, in normal'position, said stem having an annular depression for the reception of the wall a of the socket opening when the stem is swung relative to the socket: member and while in \proj ected position.

e 5'. The,--combination-with a pole, an elongated socket. at one end thereof, of a head slidably,- mounted in the socket, a pointed stem projecting from the head and beyond the socket, the wall-ofthe socket; cooperating with the stem for holding the stem against pivotal movement-when in its normal position, yieldingameansfor holding the stemnormally retracted to one, limit of its copies ofthigpatent niaygbe obtained, for. five cents each, by addressing -the 'heldiretracted by the spring, a pointed stem projecting from the head and beyond; the socket, the wallsv of the socket. coiiperating with the stem to. vhold the stem against pivotalmovement when the head isretracted.

7. The combination with a pole, a ferrule extending from one end thereof and an elongated socket at the end of the ferrule and having an opening, of ahead slidably mounted inlthe socket, as pointed stem projecting from said head and through the opening, said stem being cut away to permit swingingmovement; of the stem relative to the, socket whenthe stem is projected outwardly-relativeto the socket,anda spring housed within the ferrule and connected to the head for holding said head normally retracted, the wall of thesocket cooperating with thestem to hold said, stem against pivotal movement when retracted. a
